OBJECTIVE: To explore the association between socioeconomic status (SES) and postoperative outcomes in patients with chronic sinusitis (CRS) after functional endoscopic sinus surgery (ESS). METHODS: We conducted an observational cohort study of 1,047 patients with CRS undergoing ESS. Discharged patients were followed up to 72 weeks for all-cause recurrence events. Baseline SES was established based on occupation, education level, and family income of the patients 1 year before the operation. Kaplan-Meier method was used to calculate the recovery rate after ESS, and Cox proportional hazards regression analysis was used to evaluate the relationship between SES and prognosis. RESULTS: Patients of middle SES had lower unadjusted all-cause recurrence than those of low or high SES; 24-week overall recovery rate was 90.4% [95 % confidence interval ( CI): 89.6%-91.2%] in patients of middle SES, 13.5% (95 % CI: 12.8%-14.2%) in patients of low SES, and 31.7% (95 % CI: 30.7%-32.7%) in patients of high SES (both log-rank P < 0.001). After adjustment for covariates, hazard ratios ( HRs) were 7.69 (95 % CI: 6.17-9.71, P _trend < 0.001) for all-cause recurrence for low SES versus middle SES, and 6.19 (95 % CI: 4.78-7.93, P _trend < 0.001) for middle SES versus high SES. CONCLUSION Low SES and high SES were more associated with the worse prognosis of CRS patients after ESS than middle SES.

More than 30 years of rapid development of endoscopic surgery has led to the mainstreaming of this procedure in many surgical departments in China. Since the first report on endoscopy, it has been used in salivary gland resection for more than 20 years. The overall development of endoscopic surgery indicates that its use in oral and maxillofacial surgery is still in the early exploration stage; it has not yet been maturely developed or applied. Owing to the advancement of other disciplines and corresponding widening experiences in those fields, the development of endoscopic technology in oral and maxillofacial surgery will likely achieve a leapfrogging. Learning from the general development pattern of endoscopy, this research explores the application history, current situation, and future direction of the application of endoscopy in salivary gland surgery.

OBJECTIVE: To investigate the clinical effect of unilateral interlaminar approach 270° circular spinal canal decompression under the Interlaminar Endoscopic Surgical System(iLESSYS) Delta for the treatment of lumbar spinal stenosis (LSS) in the elderly. METHODS: Total of 29 patients with LSS treated with the iLESSYS Delta from December 2018 to January 2021 were retrospectively analyzed, including 12 males and 17 females with an average age of (71.52±10.82) years old ranging from 63 to 83 years old. All patients had definite intermittent claudication, mainly neurogenic symptoms of both lower limbs. All patients had single-level spinal stenosis, including L_3,4 5 cases, L_4,5 21 cases, and L₅S₁ 3 cases. Visual analogue scale (VAS), Oswestry Disability Index (ODI) and modified Macnab assessment criteria were used to evaluate pain, low back pain dysfunction index and clinical efficacy, respectively. RESULTS: All 29 cases were successfully completed. The operation time was (73.45±5.89) min, the intraoperative blood loss was (9.93±0.83) ml, the hospital stay was (4.03±0.41) days, and the follow-up was more than 12 months. The VAS scores of low back pain before surgery and 1 day, 1 month, 3 months, 1 year after surgery were 2.31±0.88, 1.45±0.62, 1.21±0.61, 1.10±0.55, 1.03±0.49;VAS of leg pain were 6.48±0.49 0.56, 1.97±0.61, 1.31±0.59, 1.17±0.59, 1.10±0.55;ODI scores were 38.41±2.74, 18.14±1.17, 5.17±0.53, 5.07±0.45, 4.90±0.48;low back and leg pain VAS score and ODI score have statistically significant differences between preoperative and postoperative follow-up time points (P<0.05). The MacNab efficacy evaluation at 1-year follow-up:excellent in 22 cases, good in 5 cases and fair in 2 cases. CONCLUSION The clinical effect of unilateral interlaminar approach 270° circular spinal canal decompression under the iLESSYS Delta for the treatment of lumbar spinal stenosis in the elderly is satisfactory, with the advantages of less trauma and less bleeding, large microscopic operation space, sufficient decompression, and ideal post-operative recovery, and at the same time, it can minimize the damage to the stable structure of the lumbar spine, which is an ideal surgical method for the treatment of elderly lumbar spinal stenosis.

Objective:To discuss the application of virtual endoscopy in the diagnosis of adenoid hypertrophy and the morphologic classification of adenoid. Methods:The clinical data of 97 children with adenoid hypertrophy admitted to Department of Otorhinolaryngology Head and Neck Surgery, Shenzhen University General Hospital from July 2022 to December 2022 were collected. The virtual endoscopic reconstruction of the nasopharynx was performed by cone beam computed tomography. The results of virtual endoscopic adenoid size measurement were compared with the results of nasopharyngeal CT median sagittal position and nasopharyngeal endoscopy. Virtual endoscopic classification of adenoid based on the size of the adenoids and their relationship with the torus tubarius. Results:The t-test results of the size of adenoids measured by virtual endoscopy and nasopharyngeal CT were t=1.699 and P=0.093, and the results of intra-group correlation coefficient（ICC） analysis were ICC=0.921 and P<0.01. The proportion of adenoids measured by virtual endoscopy and nasopharyngeal CT was highly consistent. The t-test results of the size of adenoids measured virtual endoscopy and nasopharyngeal endoscopy were t=1.543 and P=0.15, and the results of intra-group correlation coefficient（ICC） analysis were ICC=0.900 and P<0.01. The proportion of adenoids measured by virtual endoscopy and nasopharyngeal endoscopy was highly consistent. Among the 97 children, the morphological classification results of adenoids were 48 cases of overall hypertrophy type, 47 cases of central bulge type, and 2 cases of flat thickening type. Conclusion:The diagnosis of adenoid hypertrophy by virtual endoscopy has high accuracy, which not only avoids the invasive operation of traditional nasopharyngeal endoscopy, but also can observe the adenoid condition and its relationship with the torus tubarius from multiple angles. And, the morphological classification of adenoids using virtual endoscopy has guiding significance for perioperative preparation.

Objective:To compare the clinical effect of transaxillary non-inflatable endoscopic surgery and traditional open thyroid surgery in the treatment of PTC. Methods:A retrospective analysis was performed on 342 patients with PTC treated in the Otorhinolaryngology Department of Qilu Hospital of Shandong University from December 2020 to December 2022. There were 73 males and 269 females, aged 16-72 years, who underwent unilateral non-inflatable transaxillary endoscopic thyroid surgery（endoscopic group） and unilateral traditional open thyroid surgery（open group）. There were 108 patients in the endoscopic group and 234 in the open group. Results:The endoscopic group was lower in age（37.1±9.4 vs 43.5±11.2） years and BMI（23.4±3.4 vs 25.7±3.8 ）kg/m² than that in the open group, and the difference was statistically significant（t was 5.53, 5.67 respectively, P<0.01）. There was no significant difference in hospitalization days between the two groups（P>0.05）. The logarithmic curve of the operation time showed a smooth downward trend, and the overall operation time of the endoscopic group was relatively consistent. There was no significant difference in intraoperative blood loss between the endoscopic group（13.3±3.2） mL and the open group（14.7±6.3） mL（P>0.05）, but the operation time（130.1±37.9） min was longer than that in the open group（57.4±13.7） min, and the difference was statistically significant（t=19.40, P<0.01）. There was no significant difference in complications such as temporary recurrent laryngeal nerve injury within 3 days after operation between the two groups（P>0.05）. The aesthetic satisfaction score of the surgical incision and the incision concealment effect score in the endoscopic group were higher than those in the open group, and the difference was statistically significant（P<0.05）. Conclusion:Compared with traditional open thyroidectomy, transaxillary non-inflatable endoscopic thyroidectomy has more advantages in the concealment and aesthetics of postoperative incision. Although the former has longer operation time and more drainage, it is still a safe and feasible surgical method with good postoperative clinical effect.

Objective:To investigate the correlation between FCER2（2206A>G） gene polymorphism and the efficacy of inhaled corticosteroids（ICS） in patients with chronic rhinosinusitis（CRS）. Methods:A total of 208 CRS patients were routinely treated with functional endonasal sinus surgery and postoperative ICS. DNA extraction, PCR amplification and gene sequencing were performed to observe the FCER2（2206A>G） gene polymorphism and calculate the allele frequency. The visual analog scale（VAS） score, Lund-Kennedy score, and computed tomography（CT） Lund-Mackay score were determined 6 months after surgery among patients with different genotypes. Moreover, the polymorphism frequency was compared among different subgroups（chronic rhinosinusitis with nasal polyps versus chronic rhinosinusitis without nasal polyps, eosinophilic chronic rhinosinusitis versus non-eosinophilic chronic rhinosinusitis）. Results:There were FCER2（2206A>G） gene polymorphism in patients with CRS, and the phenotypes included 3 genotypes, AA, AG and GG, with distribution frequencies of 68（32.7%）, 116（55.8%） and 24（11.5%） cases, respectively. No significant differences were found in age, VAS score, nasal endoscopic Lund-Kennedy score and CT imaging Lund-Mackay score among patients with CRS of each genotype before surgery. In patients with the AA genotype, the changes in VAS score（5.74±1.10）, Lund Kennedy score（5.92 ± 1.14）, and CT imaging Lund-Mackay score（13.26±4.26） were significantly higher than in patients with the AG（4.37±0.86, 5.37±1.24, 10.82±3.77） and GG（4.26±0.80, 5.18±1.56, 10.10±3.53） genotype（P<0.05）. However, there were no marked difference between patients with the AG genotype and those with the GG genotype（P>0.05）. Compared with patients with non-eosinophilic sinusitis, Among them, the differences between the GG genotype and AG /AA genes were more significant in eosinophilic sinusitis compared to non-eosinophilic sinusitis（P<0.01）. Conclusion:The FCER2（2206A>G） gene in patients with CRS has genetic polymorphism and is associated with the recovery of CRS patients after surgery, individual corticosteroid sensitivity, and subgroup variability.

At present, there is no unified gold standard for the treatment of laryngeal clefts. Type Ⅰ laryngeal clefts with mild symptoms can be treated conservatively, such as thick diet feeding and using proton pump inhibitor to control reflux, while Ⅱ-Ⅳ laryngeal clefts mostly requires surgical intervention.There are many different surgical methods for the treatment of laryngeal clefts, including injection laryngoplasty, endoscopic surgical repair of laryngeal clefts and open laryngoplasty through anterior cervical approach. How to choose a more suitable surgical plan for children is a problem worth discussing. This article will review the literature on the surgical treatment of laryngeal clefts both domestically and internationally, and summarize the current situation and challenges of surgical treatment of laryngeal clefts.

Infected pancreatic necrosis(IPN) is the main surgical indication of acute pancreatitis. Minimally invasive debridement has become the mainstream surgical strategy of IPN,and it is only preserved for IPN patients who are not response for adequate non-surgical treatment. Transluminal or retroperitoneal drainage is preferred,and appropriate debridement can be performed. At present,it is reported that video assisted transluminal,trans-abdominal and retroperitoneal approaches can effectively control IPN infection. However,in terms of reducing pancreatic leakage and other complications,surgical and endoscopic transgastric debridement may be the future direction in the treatment of IPN.

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

OBJECTIVE: To compare the clinical efficacy of full endoscopic lamina fenestration discectomy (Endo-LOVE) with full endoscopic transforaminal approach discectomy in the treatment of degenerative lumbar lateral recess stenosis. METHODS: A retrospective analysis of 48 patients with degenerative lumbar lateral recess stenosis between March 2018 and March 2019 was performed. There were 32 males and 16 females, aged from 60 to 83 years old with an average of (72.9±6.5) years, course of disease ranged from 5 to 16 years with an average of (8.0±2.8) years. The patients were divided into observation group and control group according to surgical approaches. There were 28 cases in observation group, underwent Endo-LOVE surgery;and 20 cases in control group, underwent full endoscopic foraminal approach discectomy. The operation time, intraoperative blood loss, hospitalization day and complications were observed between two groups. Visual analgue scale (VAS), Japanese Orthopaedic Association(JOA), Oswestry Disability Index(ODI), lateral crypt angle were compared between two groups. And clinical effects were evaluated by modified Macnab standard. RESULTS: There was no significant difference in follow-up and operation time between two groups (P>0.05). Intraoperative blood loss was from 5 to 15 ml with an average of (8.4±3.6) ml in observation group and 5 to 25 ml with an average of (11.5±5.4) ml in control group. The hospitalization day was from 5 to 8 days with an average of (6.0±1.0) days in observation group and 6 to 9 days with an average (7.2±1.1) days in control group. Intraoperative blood loss and hospitalization day were significantly lower in observation group(P<0.05). There were no serious complications in both groups. The VAS, JOA scores, and ODI at 3-month and final follow-up were significantly improved in both groups (P<0.05), and observation group was significantly better than control group (P<0.05). The skeletal lateral crypt angle and soft lateral crypt angle were significantly greater than the preoperative angle at 3 days postoperatively(P<0.05), and observation group was significantly better than control group(P<0.05). At the final follow-up, the modified Macnab criteria was used to assess clinical efficacy, in observation group, 22 patients obtained excellent results, 5 good and 1 fair;while 11 excellent, 4 good and 5 fair in control group;the clinical efficacy of observation group was significantly better than that of control group(P<0.05). CONCLUSION Both surgical methods are performed under direct vision, with high safety and good clinical efficacy. However, Endo-LOVE enlarged the lateral crypt more fully.
